Having any item in the inventory (may specifically be in hand) causes 9 achievements. Happened when I was in creative mode so I do not know if it affects survival.

Achievements:
[A Quite Spiritual Substance]
[Soul Forgery]
[A new Beginning]
[Spiritual Implements]
[Focal Point]
[Not Suited For Jewelry]
[Staff of Office]
[Psychic Braiding]
[Prestidigitator]

Mod Version: [1.17-pre4] Conjuring 2 - 1.0.1

Maybe actually closing this back when I fixed it might have been a good idea.

Anyways, it's fixed
